I would have dificulty without tabbed browsing. At the moment I have a dozen tabs open, along with a half dozen applications running, so i'd hate to see my task bar if I did not use tabbed browsing.
I don't care much for Firefox, and we all know that IE sucks eggs. I once used Lotus Notes which has decent tabbed browsing, now I use another product called Avant Browser (
http://www.avantbrowser.com).
I have a friend who uses Safari for Windows, but I've never tried it. I like Avant Browser well enough that it's all I use.
